Given numbers are 257, 915, 668, 504

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 915 are 3 x 5 x 61

Prime factors of 668 are 2 x 2 x 167

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 257, 915, 668, 504

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(257, 915) = 235155

GCD(257, 915) = ( 257 x 915 ) / 235155

= 257 / 915

= 257

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

So, Greatest Common Divisor of 257, 915, 668, 504 is 1
